Definitions
- the present invention relates to a fixing assembly, capable of fitting spectacles with supplemental lenses which serve as filters, protective shields and/or magnifying glasses over a restricted sub-area of the actual lenses.
- the fixing assembly includes mechanical holders which enable the positioning, aligning and/or maintaining the alignment of supplemental lenses.
- the dentists have a need to wear a protective shield for blocking the radiation of a UV-curing device from striking directly on the eyes.
- a separate UV-protection shield held by a dental assistant is inconvenient to use.
- the protection can be applied to any ophtalmologically harmful radiation.
- the separate lenses may also serve as filters for making certain objects more clearly detectable.
- the spectacles be provided with a magnifying sub-area that can be used in precision work which requires magnification from time to time. Manufacturing special bifocal glasses for this purpose is expensive.

Abstract
Description
- The present invention relates to a fixing assembly, capable of fitting spectacles with supplemental lenses which serve as filters, protective shields and/or magnifying glasses over a restricted sub-area of the actual lenses. The fixing assembly includes mechanical holders which enable the positioning, aligning and/or maintaining the alignment of supplemental lenses.
- For example, the dentists have a need to wear a protective shield for blocking the radiation of a UV-curing device from striking directly on the eyes. A separate UV-protection shield held by a dental assistant is inconvenient to use. In addition to UV-radiation, the protection can be applied to any ophtalmologically harmful radiation. In addition, the separate lenses may also serve as filters for making certain objects more clearly detectable.
- On the other hand, it is often desirable that the spectacles be provided with a magnifying sub-area that can be used in precision work which requires magnification from time to time. Manufacturing special bifocal glasses for this purpose is expensive.
- A fixing assembly of the invention can also be used for fitting the spectacles with binocular loupes, comprising an attachment frame and two loupes, each provided with at least two lenses of which the ocular lens closer to the eye is smaller than the outer objective lens.
- Such binocular loupes to be attached to spectacles are intended to facilitate precision work, such as the work of a dentist or of a precision mechanician. The drawbacks of prior art binocular loupes include a complicated design and an excessive weight as well as a restricted field of vision caused by the loupes.
- US Patent publication 5,182,588 anticipates the attachment of a protective coating to the surface of spectacle lenses over a restricted sub-area of the lens. A thin surface coating is difficult to manufacture and it alters the spectacles permanently and, thus, the solution is poorly adaptable to spectacles adjusted to each individual's own eyes. Furthermore, the coating formed by a thin layer is difficult to provide with a sufficient protective effect if clear transparency is desired at the same time. The coating only offers protection and does not provide a possibility of using simultaneously or alternatively a magnifying glass or a binocular loupe.
- Moreover, e.g. Patent publications US-4,647,165 and US-3,446,548 disclose the placement of various supplemental lenses over a sub-area of the actual lenses by means of mechanical, adjustable arms. These prior art solutions do not afford a reliable attachment for supplemental lenses and the attachment arrangement is not suitable for all types of spectacles. The attachment is often secured by manufacturing specially designed spectacles, leading to a substantial increase in total costs. The most general drawback in prior art attachment units based on mechanical attachment arms is the fact that the attachment assemblies obscure and interfere with the field of vision.
- An object of the invention is to provide a fixing assembly for attachments mountable on the user's own spectacles, said assembly being as inconspicuous, easy to use and economically priced as possible and versatile in applying it to fixing various attachments. In the attachment of binocular loupes, for example, it is important that the fixing assembly and the loupes screen as little as possible of the field of vision, whereby the view can be readily directed past the loupes at the same target that has just been examined and magnified through the loupes.
- A particular object of the invention is to provide a fixing assembly for supplemental lenses and/or binocular loupes, which is suitable for use in connection with many different types of spectacles.
- These objects are achieved on the basis of the characterizing features set forth in the annexed claim 1. Preferred embodiments of the invention are set forth in claims 2-8.
- For example, the use of resiliently flexible arms (claim 2) offers substantial benefits if compared to rigid hinged frames. The lenses carried by flexible arms are readily cleanable and return to the original position thereof.
- The non-independent claims 9-13 disclose preferred embodiments of the invention assisting in the individual focusing of loupes for setting the loupes precisely according to the ocular gap of a user and for minimal screening of the field of vision caused thereby.

Supplemental lenses 4 protecting from ophtalmologically harmful radiation and/or serving as magnifying glasses and/or as filters are positioned on the inside surface of actual lenses 1 adjacent to the bottom edge of the lenses 1. Attachment of thesupplemental lenses 4 is effected by means of resilientlyflexible arms 5, comprising e.g. steel wire. The bottom ends of saidarms 5 are fixed by means of an adhesive in a slot made in the bottom edge of thesupplemental lenses 4. The top ends of saidarms 5 are secured to ametal clip 6 that can be tightened with ascrew 7. Themetal clip 6 is in engagement with abridge 3 connecting rims oreyewires 2 of the actual lenses across the nose. - The
metal clip 6 includes twobody members arms 5 therebetween by tightening thescrew 7. Aclamping loop 10 made of a flexible, soft metal, e.g. silver provides a gripping yoke around thebridge 3. The ends of saidclamping loop 10 are received in ahole body members screw 7 such that the screw threads engage with the material of theclamping loop 10. Theclamping loop 10 can be provided with existing threads or those may be a result of cutting by the screw. Such a clip assembly makes it possible that asingle screw 7 be used for clamping the clip securely to thebridge 3 and at the same time for pressing thearms 5 into the engagement with the clip. The surface of saidclip body member 8, facing theother body member 9, is provided withgrooves 12 less deep than diameter of thearms 5 for receiving saidarms 5. Thus, thearms 5 retain the alignment thereof and, prior to final tightening of thescrew 7, the length of thearms 5 can be regulated by a longitudinal adjustment thereof between thebody members supplemental lens 4 in a proper position. Finally, the extra length from the top ends of thearms 5 can be cut off. If the arms cannot be fixed from below, it can be done from above by bending down the arms extending from the top edge of the clips. - In addition, the
body member 8 of theclip 6 is designed for an engagement with a yoke-like holder 14 mounted on the base of anarm 15 supporting a separate magnifying and/orprotective glass 16. The yoke-like holder 14 is pressed from above on top of thebody member 8 with ribs included in the inner surfaces of theyoke 4engaging grooves 13. This type ofmagnifying glass 16 in association with spectacles is prior known but, according to the invention, it is attached in a new fashion by means of alightweight holder yoke 14 to ametal clip 6 of the invention. - Fig. 2 shows in more detail the possibility that the bottom half of a
supplemental lens 4 comprises a protective glass 4b and the top half a magnifying glass 4a. In this case, aseparate magnifying glass 16 is not needed. Alternatively, either one of themagnifying glasses 4a or 16 can be a filter or a combination of a filter and a magnifying glass. - The following description deals with the exemplary embodiment shown in figs. 7-10.
-
Binocular loupes 18 are fastened by means of abracket 17 to anose bridge 3 included in spectacles. Eachloupe 18 is fitted with at least two lenses of which the ocular lens closer to the eye is smaller than the outer objective lens. As for its outer surface, aloupe jacket 19 connecting the lenses also diverges at a sector angle which is essentially consistent with that drawn from the pupil to the rim of the ocular lens. Thus, restriction of the field of vision caused by the loupes is minimal. The user is able to look through or past the loupes according to his or her choice by just slightly turning the viewing direction and the head. - The
loupe jackets 19 may consist of tubes having a thin wall thickness and a conicity which is consistent with said sector angle. The loupe jacket material may be a metal, fiber-reinforced plastics etc. The loupe jacket may have a cross-section which is circular, elliptical or polygonal. - The
loupes 18 are mounted onflat crossarms 20 which can be bent at hinge points 21 that are made of a metal and have a shape which changes as a result of bending. The hinge points 21 can be made of a material other than thearms 20, e.g. wire threads embedded in the arm material which is e.g. light metal or fiber-reinforced plastics. The axial directions ofhinges 21 are selected so as to control bending of thearms 20 such that, in various positions of theloupes 18, the centre axes thereof cross each other at essentially the same distance from thebinocular loupes 18. Thus, the loupes always remain on focus provided that the distance between the loupes is set according to the distance between the eyes. - At the mid-point thereof between the
hinges 21, saidcrossarms 20 are connected to a lengthwise arm 24 whose attachment point is also provided with a hinge 22 made of a resilient metal. The arm element 24 is provided with alengthwise slot 28 and thearm element 26 with acrosswise slot 27 and, thus, attachment of thearm elements 26 and 24 to each other by means of ascrew 25 affords both a lengthwise and crosswise adjustment. Thearm element 26 is connected with a hinge 23 to a yoke-like clip 6a which is mountable from above (or from below) on ametal attachment body 6b, having its sides provided withgrooves 6c and the inner surfaces of the yoke 6a being shaped accordingly. In this case, themembers 6a and 6b together provide an attachment clip, generally designated byreference numeral 6. With this snap-fit coupling, the binocular loupes are readily removable and replaceable. The small-sized andinconspicuous attachment body 6b can be permanently fixed to thenose bridge 3 of spectacles. Theattachment body 6b can be fixed to nearly all types of spectacles by using aclamping hook 10, made of a soft metal and constituting a loop which grips around thenose bridge 3 and whose ends are received in a hole extending through theattachment body 6b and dimensioned identically to the hole in themember 8 in fig. 6, i.e. in such a manner that the threads of ascrew 7 engage with those of the clampinghook 10. Such a clip is small, inconspicuous and firm and adaptable to nearly all types of spectacles. - What is essential about the invention is that the fixing assembly and the loupes are lightweight and only obscure a small section of the field of vision. This objective can be favouved even further by designing a thin-walled loupe jacket so as to comply with the sector angle of a field of vision covered by a small-sized ocular lens. In addition, the flat shape and positioning of attachment arms are selected so as to interfere minimally with the field of vision. At the same time, however, the attachment arms, with the aid of their hinge points, enable an individual alignment and setting of the distance between the eyes, such that the loupes have a focus always fixed in position.
The loupes may have a length of e.g. 20 - 30 mm. The ocular lens may have a diameter of e.g. about 10 mm. The ocular lens' distance from the eye is in the order of 20 mm when the lens is positioned very close to the lens of spectacles. The objective has a diameter which is determined by the sector angle and the length of the loupes.
